摘　　要：目的探讨肠外瘘分型的CT表现。方法对754例肠外瘘进行CT检查。参照临床分型．将肠外瘘分为管状瘘和唇状瘘2个类型，分别分析它们的CT征象。结果本组管状瘘518例（68．6％）．其CT征象为内、外口之间形成不均匀的管道；唇状瘘236例（31.4％），其CT征象特点是较大的外口呈唇状改变。肠外瘘的肠管和腹腔内改变表现为炎性病灶，其中管状瘘的腹腔和腹膜后脓肿发生率明显高于唇状瘘（P〈0．01），而唇状瘘的肠壁炎性改变发生率较高（P〈0．01）。结论肠外瘘具有特征性CT表现，CT检查有助于显示肠外瘘外科分型的影像学征象。Objective To discuss the computer tomography （CT） appearances of the enterocutaneous fistula classification. Methods CT scan was performed on 754 patients with enterocutaneous fistula, which were divided into tube fistula and labiate fistula according to clinic classification, and the appearances of CT scan were analyzed respectively. Results Five hundreds and eighteen patients （68.6%） were diagnosed as tube fistula, and CT appearance of which was a duct formed between internal hole and external hole. Two hundreds and thirty-six patients （31.4%） were diagnosed as labiate fistula, and CT appearance of which was a large external hole like labium. The basic appearance of intestine and celiac cavity in enterocutaneous fistula was inflammatory focus. The incidence of abscesses in tube fistula was higher than that in labiate fistula （P 〈 0.01）. The intestinal inflammation was more common in labiate fistula than that in tube fistula （P 〈 0.01）. Conclusion There are characteristic CT appearances in enterocutaneous fistula and CT scan is useful for classification of enterocutaneous fistula.
